Laura Dern in talks to star with Kristen Stewart in JT LeRoy biopic

Laura Dern is in talks to star with Kristen Stewart in the forthcoming biopic 'JT Leroy'.

The 50-year-old actress - who is currently on screen in HBO sitcom 'Big Little Lies' - will join the Twilight alumnus in the title that will tell the story of Savannah Knoop, who tricked the rich, famous and elite in Hollywood and the literary and fashion worlds into believing she was a transgender man known as Jeremiah "Terminator" LeRoy, or JT LeRoy for short.

JY LeRoy was, in fact, a literary persona created by Knoop's sister, the writer Laura Albert, in her 1999 debut novel 'Sarah'.

For six years Knoop would parade herself as LeRoy and kept her real identity under wraps while her sister Albert continued to write LeRoy's works and give interviews as LeRoy in email and on the phone.

Then in 2005, The New York Times outed the pair and revealed that LeRoy, who always donned a black hat, blonde wig and sunglasses, was a fictional persona.

Knoop retold their story in her 2008 autobiography 'Girl Boy Girl: How I Became JT LeRoy' and Justin Kelly has adapted the script for the upcoming movie and he's also is attached to direct.

Stewart, 26, is set to portray Knoop and if Dern takes the role, she'll star as Albert.

Dern rose to fame in the 1986 cult classic 'Blue Velvet' and went onto star in romantic thriller 'Wild At Heart' with Nicholas Cage (1990) and the original 'Jurassic Park' movie (1993) alongside Sam Neil.

The actress was last seen on screen mothering Reese Witherspoon in 'Wild' but has a busy 2017, with parts in Disney's 'Star Wars: The Last Jedi' and Jennifer Fox's drama 'The Tale'.
